Cryogenic thermo-optic response of low-loss phase change material for non-volatile photonic phase shifter
Marcus Tamura, Chuanyu Lian, Hongyi Sun +8
Phase change materials (PCMs) can enable non-volatile optical memory through the large refractive index and extinction coefficient contrast between crystalline and amorphous states…
Photonic Theta Cavity: Engineering Bound States in the Continuum in Topological Resonators Beyond the Limitations of Near Field Coupling
Eric Seabron, Robert E. Coleman, Chuanyu Lian +3
The Theta Cavity is a unique topological resonator architecture which utilizes interferometric coupling to overcome fundamental design limitations associated with near-field evanes…
Ultrawide-angle diffraction-limited 2D beam steering via hybrid integrated metasurface-photonic circuit
Zhiping He, Luigi Ranno, Padraic Burns +12
Two-dimensional (2D) wide field-of-view (FOV) beam steering is a key enabling capability for emerging free-space optical systems, including inter-satellite optical links, airborne…
Incorporating Si into Sb2Se3: Tailoring Optical Phase Change Materials via Nanocomposites
Chih-Yu Lee, Yi-Siou Huang, Felix Adams +10
Chalcogenide-based optical phase change materials (OPCMs) exhibit a large contrast in refractive index when reversibly switched between their stable amorphous and crystalline state…
High-Speed Multifunctional Photonic Memory on a Foundry-Processed Photonic Platform
Sadra Rahimi Kari, Marcus Tamura, Zhimu Guo +9
The integration of computing with memory is essential for distributed, massively parallel, and adaptive architectures such as neural networks in artificial intelligence (AI). Accel…
Microheater hotspot engineering for repeatable multi-level switching in foundry-processed phase change silicon photonics
Hongyi Sun, Chuanyu Lian, Francis Vásquez-Aza +9
Nonvolatile photonic integrated circuits employing phase change materials have relied either on optical switching mechanisms with precise multi-level control but poor scalability o…
Nonvolatile Tuning of Bragg Structures Using Transparent Phase-Change Materials
Nicholas A. Nobile, Chuanyu Lian, Hongyi Sun +7
Bragg gratings offer high-performance filtering and routing of light on-chip through a periodic modulation of a waveguide's effective refractive index. Here, we model and experimen…
